"Roald Zinnurovich Sagdeev (Russian: Роальд Зиннурович Сагдеев, Tatar: Роальд Зиннур улы Сәгъдиев born 26 December 1932) is a Russian expert in plasma physics and a former director of the Space Research Institute of the USSR Academy of Sciences. He was also a science advisor to the Soviet President Mikhail Gorbachev. Sagdeev graduated from Moscow State University. He is a member of the Russian Academy of Sciences. He has worked at the University of Maryland, College Park since 1989 in the University of Maryland College of Computer, Mathematical, and Natural Sciences. He is also currently a Senior Advisor at the Albright Stonebridge Group, a global strategy firm, where he assists clients with issues involving Russia and countries in the former Soviet Union. Sagdeev was married to, and divorced from, Susan Eisenhower, granddaughter of Dwight D. Eisenhower. Sagdeev was the recipient of the 2003 Carl Sagan Memorial Award, and the James Clerk Maxwell Prize for Plasma Physics (2001)."
"Sagdeev was one of a few of Lev Landau's students, the Soviet Nobel laureate. In the dormitory he lived next to Mikhail Gorbachev, a law student, and Raisa Gorbachyova, a sociology student.
At the age of 35, he was one of the youngest persons ever elected as a full academician of the Academy of Sciences of the USSR. From 1970 until 1973, he worked at the Institute of Physics of High Temperatures of the USSR Academy of Sciences. His work on the behavior of hot plasma and controlled thermonuclear fusion in both the Institute of Atomic Energy and later at the Institute of Nuclear Physics have won international recognition."

Side notes of Sagdeev's dormitory neighbors:
"Mikhail Sergeyevich Gorbachev (born 2 March 1931) is a Russian and former Soviet politician. The eighth and last leader of the Soviet Union, he was the General Secretary of the Communist Party of the Soviet Union from 1985 until 1991. He was also the country's head of state from 1988 until 1991, serving as the chairman of the Presidium of the Supreme Soviet from 1988 to 1989, chairman of the Supreme Soviet from 1989 to 1990, and president of the Soviet Union from 1990 to 1991. Ideologically, Gorbachev initially adhered to Marxism–Leninism, although he had moved towards social democracy by the early 1990s."
